The laboratory door opens as a masked doctor approaches a nurse tied to the examination table. She writhes her body, yet can't help trembling under the doctor's invasive examination. He meticulously probes her sensitive areas, visibly surprised by her clitoral response. Speaking harshly, he treats the session as discipline. He rips off her panties and begins inspecting her inner parts—unable to endure, the nurse cries out. "Iku iku!" she moans obscenely, repeatedly screaming as the once-pure angel in white reveals her shameless, aroused state.
